'z claims; (c1. 299-78) This invention relates to air dispensing equipormember-BS having vlap-finished steel bearing ment. face 34 against the ring 29. This ring 33 is press This invention hasl utility when incorporated fitted intoseat 35 of sleeve 36 having externally in pneumatic joints for self retrieving reels for threaded portion 37 coacting with internally tire charging at automobile service stations. threaded portion 38 of the housing-14. The hous- 00 Referring -to the drawing:A v l ing 14 is additionally providedwith tapered seat Fig. 1 is a side elevation, with parts broken face 39 in snug tting relation with which may away, of an embodimentof the invention; be located taper seat portion 40 of this sleeve 36 Fig. 2'is a detail view in side elevation` of the having polygonal terminus 41 as a nut.

10 fitting unit or joint of Fig. 1; As assembled in the housing 14, there is swivel 6 5 Fig. 3 is a view from the rightof the device of connection in that the tting 11 is held against Fig. 2; rotation by the block 6, while the housing 14 as Fig. 4 is a section on the line IV-IV, Fig. 3; engaged by the pin 24 rotates with the reel 18 and and carries therewith the sleeve 36, ring 33 and Fig. 5 is a section on the line V-V, Fig. 4. holding clip or ring 42, as well as a cylindrical 7G Standard 1 is shown as having pressure air member or oil-less wood lateral bearing 43 for the supply line 2 extending to regulator valve 3 in the section 11. The clip 42 oiers resistance to relative upper portion of the standard 1 as adjusted by longitudinal shifting between the element 11 and hand wheel 4 (U. S. Patent 1,736,274, Morley, the packing 28. This leaves the non-rotating Nov. 19, 1929). This air supply ilows thence by parts as the tting 11, the cushion or axially 75. line 5 to block 6 shown as mounted by standard effective take-up means 28, and the bearing plate 7 in shell or enlargement 8 of the standard l. or disk 29. The rotation is thus limited to occur This block 6 is shown as having internally threadbetween the steel ring 33 and the bronze plate or ed port 9 coacting with externally threaded pordisk 29.

125 tion 10 of fitting 11 shown as having port 12` Air under pressure coming into the tting 11 8G therethrough with clearance chamber 13 in h ousand passing by duct 12 into the chamber 13 estabing 14 having branch way 15 from which exlishes a pneumatic load holding the compression tends duct 16 to coupling 17 fast with reel 18 ring 28 asaresilient check controlinthrusting the on bearing 19 iixed with the standard 1. disk 29 against the bearing face 34 of the ring 33.

From this coupling 17 extends hose 20 for wraps This is accordingly a pneumatic cooperative 85 21 about the reel 18 and passage therefrom means maintaiinng the gland at all times tight through opening-22 in the standard where such under a pneumatic action. hose is terminally equipped with valve herein For taking down this joint it is only necessary shown as check valve or tire chuck terminus 23', after removing the block 6 to back off the nut which as depressed over a tire valve opens the portion 41 and thus remove the sleeve 36 and its 90 check to allow the adjusted pressure flow of air assembled parts thereon in breaking the air-tight from the supply line 2 past the regulator valve 3 joint 39, 40. The rotative and non-rotative parts and through the hose to the tire. are thus in assembly and the tting 11 may be now The block 6 is held by the standard 7 against thrust clear out of the bearing 43 to carry with it rotating with the reel 18, while the housing 14 as the disk 29 and packing 28. 05 located adjacent the end of the reel and clear It is thus seen there is in this device as assemthereo is axially of such reel and held for rotabled a pneumatic holding effectiveness for taketion therewith by pin 24 from the reel engaging up on a thrust bearing seat with the unit load the fork 25 of arm 26 from housing 14. carried by the lateral oil-less bearing 43 and all The pressure holding device or connection is in this apart from the reel structure proper. Auto- 100 the unit assembled with the duct section fitting matic retrieving means 44 are provided for the or member 11 herein shown as provided with reel 18. shoulder 27 against which is located elastic gas- The automatic retrieving means as winding the ket or rubber composition packing 28 as a seat hose 21 on the reel bring collar or rubber shoulder for sheet metal bronze bearing disk 29 having 45 adjacent the chuck 23 into abutting relation 105 tongue 30 engaging in notch 31 of the overhang adjacent the opening 22 in a rel-winding speed so 32 from the shoulder 27. The bearing disk 29 is that the hose 21 is gradually and smoothly reaccordingly held against rotation relatively to tracted into the housing 8 bringing this rubber the duct section 11. shoulder 45 against the openings 22 where hood Opposing this bearing disk 29 is bearing ring 57' may be swung up to eye 58' and lock applied. 1 10 This protects the housing against unwarranted withdrawals in periods of non-use or non-exposure for use of this air service device.

What is claimed and it is desired to secure by Letters Patent is:

1. lA reel rotation effecting means extending parallel to the reel axis and away from the reel, a tubular swivel joint embodying a housing, a support for the housing independent of the reel and coaxial with the reel, said housing having means loosely acted upon by said rotation effecting means for causing the housing to rotate with the reel, said joint having a. radially extending connection adapted to engage a ilexible tubular'duct on the reel.

2.`For a reel hose supply connection, a swivel joint, there being mounting means for the joint independent of the reel and independent of the support for the reel, loose connection means extending from the reel for turning'the joint with the reel, and a conduit from the joint to the hose on the reel.

3. For a reel hose supply connection, a swivel joint, there being mounting means for the joint independent of the reel and approximately coaxial with the reel, a housing for the joint having a radial extension. loose connection means from the reel engaging said extension for rotating the joint housing with the reel, and a conduit from the joint to the hose on the reel.

4. In combination, a hose reel supported at one side for rotation', a supply connection swivelly, concentrically and independently mounted at the other side o1' said reel, a projection from said reel loosely engaging said connection to cause the connection to be rotatable with said reel, and a flexible rotatable with said reel, and a flexible conduit leading from said connection to the hose in said 6. In combination, a hose reel supported at one side for rotation, a supply duct, a non-rotatable `fitting terminus for the' duct, means mounting said terminus centrally of the reel at the side of the reel opposite to'that on which the reel is supported, a companion tting rotatably mounted as to said terminus tting and therewith forming sections of a swivel joint, a projection from the reel loosely engaging said companion fitting to rotate said companion tting with the reel, and a flexible conduit leading from the companion fitting to the reel.

' 7. A duct providing swivel joint including relatively rotative members, one of which is angular, a reel adapted to carry wraps of tubular means having communication with the angular member of the joint, supporting means for the other member of the joint for locating the joint axially of the reel, and loose connection cooperative means between the angular member and the reel for holding the reel and angular member for common rotation.
